A new species, Pagastia hidakamontana sp. nov., is described from the alpine zone of the Hidaka Mountains in Hokkaido, Japan. Pagastia orthogonia Oliver, so far known only from the Nearctic Region, is newly recorded from Japan and redescribed. Females of P. lanceolata (Tokunaga) and P. nivis (Tokunaga) are redescribed, and the synonymy of P. lanceolata with Syndiamesa (Lasiodiamesa) crassipilosa Tokunaga (= Pseudodiamesa crassipilosa ) is proposed. Keys to males and females of Japanese species of the genus are provided.
